Functionalities of Different Functions
Explore how to use Kotlin Flow lifecycle functions such as onEach, onStart, onCompletion, onEmpty, and catch to manage data streams effectively. Learn to react to emitted values, handle flow start and completion, manage empty flows, and catch exceptions for robust coroutine-based applications.

When flow is completed or an exception occurs, this information is also propagated, closing the intermediate steps along the way. So, as they all flow, we can listen for values, exceptions, or other characteristic events (like starting or completing) using methods such as:
